Pennsylvania has approved the use of drip irrigation as an alternate wastewater disposal method for on-lot sewage. Smooth, graded, gravity-driven slopes suit surface irrigation best. Low labour and relatively low operation cost. No soil erosion. ... A zero value represents land use types that limit the suitability of land for surface irrigation such as water bodies, wetlands, urban areas, forest, and protected areas. Pumps commonly used for irrigation fall into two broad categories: Displacement Pumps and Centrifugal Pumps. For properties where surface irrigation of treated effluents is not acceptable, drip irrigation is a very viable alternative for homeowners who wish to reuse all of their water for landscape watering, or for lots where preservation of trees is a high priority. Advantages include low costs and minimal labor. Irrigation should be optimum because even over-irrigation can spoil the crop production. In fact, in the United States in 2000, about 29.4 million acres were irrigated by flood irrigation as compared to about 28.3 million acres irrigated by spray irrigation. Subsurface application of water aimed directly at the root zone improves yields by reducing the incidence of disease and weeds. Contractors, architects, designers and engineers alike are now able to benefit from the wide spectrum of information that has been gathered from numerous sources into a single document. But best of all they are not that hard to install. There are numerous types of pumps designed for various purposes. Controlling irrigation-induced soil erosion is one of the important issues of irrigation management and surface water impairment. Distribution manifolds should be 25 mm uPVC or polyethylene pipe buried 300 mm below the ground surface. irrigation water-p roduction wells, g oundwater quality and long-term g oundwater supply are the most important considerations.
